As someone in SF, I feel this.
Luckily the venue I'm going to in a few weeks has a large parking garage nearby that you need an access code to enter at night. Still not enough to stop break-ins here, which are rampant, but it helps.
Main thing that I live by in the Bay Area, which sucks but is necessary: leave nothing in your car every, no matter where. At the coast, we'll leave sweaters in the car, but I make sure to stretch them to show they're not covering anything.
I can't count how many broken windows I've seen. Even a few months back, a nice older Indian family at the coast waved us down, and they were on the verge of tears. They were in a nice rental SUV, very expensive, and had just arrived to SF that day. They parked at a viewpoint for less than 5 minutes, and a fucking brand new Tesla rolled up, stole all of their luggage, and left.
They were crying, saying they arrived for some medical convention, and never could imagine it happening in America of all places. Lost their passports, medications (for an older ladies heart,) plus all laptops and cash.
At this point, I think all arrivals in SFO should get a pamphlet on leaving nothing in your car; I know personally way too many horror stories.
Long ass story, but I'm procrastinating and totally get the frustration with this shit. It's not normal, and most of the developed world doesn't have to worry about this crap.
(Pumped for the show though!)
